This trial will recruit 38 women between 18 and 45\u2005years of age with secondary dysmenorrhoea with uterine fibroids. The investigational drugs, either GBH or placebo, will be administered to the participants three times per day for two menstrual periods (8\u2005weeks). The participants will be followed up for three menstrual cycles after administration of the drugs. The primary outcome will be the Numeric Rating Scale score of average menstrual pain. All analyses will be performed with SAS (V.9.1.3; SAS Institute, Cary, North Carolina, USA) by a statistician blinded to the allocation of the groups. Statistical analysis will be undertaken on the intent-to-treat (ITT) basis with a 95% CI using the last observation carried forward for missing values. The ITT analysis will include all randomised patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This research protocol has been reviewed and approved by the institutional review boards of the trial centre (number WSOH IRB 1606-03).
